Cheapest rust proof coating on top of rust?

Depends on how bad the rust is and what you are doing. If you're painting over it even por15 isn't a permanent solution and it can continue to rust underneath it ending up worse then when you started. Anything non drying like Krown, Rust Check or fluid film are the best ways of protecting it.
It's a worktable I'm building from scrap that'll end up indoors at some point, I just don't see the point of grinding all that rust off if I can avoid it.
rust indoors creeps much slower than outdoors . when you bring it inside, scuff off the surfaces you want to look nice & call it done.
yeah, after watching some vids, looks like rustoleum is the way to go. There's a 'rust reformer' and 'rusty metal primer' that may be worth a shot but the later is a ****** color and the former only comes in a rattle can.

Your answer is Woolwax and they are currently having their Memorial Day 20% off sale (promo code: freedom). Just use compressed air to blow off the loose scale, hose it down and apply....

I’ve had great luck with a spray can of Rustoleum rust reformer. I gouged the rear of my Ridgeline on a mailbox many years ago. Initially o just sprayed gloss black Rustoleum on it but the rust returned. Frustrated, one day I sprayed it with the rust reformer and the rust has never came back. That has got to be at least five years ago now. Sadly, repairing it correctly is low on the priority list. I also sprayed the rust reformer on the undercarage that year. It’s still holding up great.

I wouldnt want a Krown or other "Oil" style treatment on a workbench. In the heat, it will run and I wouldnt want to rub up against it. Krown or Rustcheck is the best out there for vehicles IMHO.
Id brush it off with a wire brush, then shoot it with some Rustoleum Red Primer. Inside, it will last a long time.

Another vote for rustoleum. Will look great for years inside on benches/equipment etc.
Same as anything it will look as good as the effort you put into it. At the least knock off any heavy rust, wipe down with acetone and giver.

I am wondering about the prep. I'm hesitant to wire brush as this just creates a rust dust layer. I hear you on the heavy scale and I think POR's best result is after using a needler, which is way too much work for my purpose over just using a grinder. I'm thinking I'll use a degreaser first and power washer 2nd then letting it air dry & give it a paint thinner wipe prior to paint last. Power washer should knock much of what would've chipped/blown away.

Clean and degrease it as you're planning then just get some naval jelly. It's basically the active ingredient in the rust removers without primer mixed in (i.e. Rustoleum). Phosphoric acid that converts iron oxide to a phosphate coating. Simple, cheap, and has been around for centuries.
